Can we pass class objects as function arguments? Explain with the help of an example.

 #include <iostream>

using namespace std;

class a

{

public:

    void show()

    {

        cout << "hello\n";

    }

    void show2(a A)

    {

        A.show();

    }

};

int main()

{

    a A,b;

    A.show2(b);

    return 0;

}

//first one is using method

#include <iostream>

using namespace std;

class a

{

public:

    void show()

    {

        cout << "hello\n";

    }

   

};

void show2(a A)

    {

        A.show();

    }

int main()

{

    a A;

   

    show2(A);

    return 0;

}

//this one is using function
